I made these coasters as a present a while back for a friend. I wanted to make some more- and realized that I forgot how I did some of it. Looks like instructables is going to help me in the future in more ways than I initially imagined. As I take classes at the TechShop the options for a project continue to expand. I took the table router class just hours before I realized that it would help me complete the coasters quicker with higher consistency.
